Accor is doing it's almost yearly year-end supersale. It's 50% for Aclub members and 40% otherwise. I would recommend just signing up for Aclub. Sale ends 25th November for stays between 11 December 2011 and 12th February 2012. There are some pretty good hotels like the Vie in Bangkok that we previously stayed up for grabs. The only exclusion from this sale are Sofitels.
